What did you expect ?.
This is a first generation device, and at a bottom-feeder/consumer price.
Testing time is expensive; if you want Min/Max guarantees,
you will need to pay more to get that.

Thanks Kevin. A look at the graph shows why it's a graph & not a formal
specification. Atmel's documentation can be a bit vague at times.

Jim - thanks. I had thought maybe you were writing a magazine article.
Concerning the atiny11b, will the change cause you any major reworking?

I did a new design last month using the
ATTINY11. I don't want to program thousands
of ATTINY11's at my desk so I sent the hex
code to digikey so they could program them
for me. They happily did that, sending me
a "first article" to approve. One month
later, they told my purchasing lady that
the ATTINY11 was obsolete.
A "first article" is the first copy of
a custom or fabricated device that is sent
to the designer so that he/she can verify
that it meets specification.

Jim - I've missed your meaning. What do you mean by "first article with
digikey" and "preprogrammed atiny11".

Can't speak to that. If you're
working on a new design, be aware
that the ATTINY11 appears to be
going obsolete. After doing a first
article with Digikey last month for
a preprogrammed ATTINY11, they told
me that I had to convert to the
ATTINY11B.

See page 69 - for the ATTiny11 the watchdog oscillator is used when
you select internal clocking.

comp.arch.embedded
Atmel atiny11 internal clock range
Has anyone seen a min/max spec. for Atmel's atiny11? The documentation here is dated 07/06, presumably june, 2006 and states only 1 megcps; no range, no thermal coeficient.
